Full textAbstract:
The Gorham Proverbs Test was administered to 278 black participants residing in a large metropolitan area in Southern California. Respondents were also asked to indicate whether they were familiar with each of the 40 proverbs in the test. Scores were significantly affected by respondents' ages, education, and perceived childhood socioeconomic status. Familiarity with a proverb increased the probability of its correct interpretation. Familiarity of proverbs and attempts to interpret them were significantly associated, that is, respondents tended not to attempt interpretation of unfamiliar proverbs. The number of familiar proverbs per test was not significantly associated with respondents' test scores. The mean Abstract score obtained in this study was comparable to mean scores previously reported in the literature, suggesting that ethnic differences do not significantly affect performance on the Proverbs Test.

Full textAbstract:
Color is a symbolic expression tool used by humans to translate the intentions and ideas of its users, not exception the color names used in proverbs. This research is a qualitative descriptive which aims to describe the meaning of Madurese proverbs which contain color name elements and their relation to the Madurese life principles. The data of this study are Madura proverbs which contain color name elements. Furthermore, primary data sources come from informants and secondary data sources come from books and internet pages. Data were analyzed using an ethnolinguistic approach with ethnoscience methods. The results showed that 6 Madurese proverbs used the color name elements. The colors are potѐ ‘white’, celleng ‘black’, and konѐng ‘yellow’. Each same color can have a different meaning in each proverb. Besides, the six proverbs that use the color name elements become Madurese life guidelines in running their life, such as having to maintain self-esteem, be humble, avoid abuse of power, keep trying, be a person who has good character, and associate with people who bring benefits. Thus, this research is fundamental because the color is not just a symbol of beauty, but it can show the culture of its users in the form of language expression.

Full textAbstract:
Hunger and inadequate nutrition are ongoing concerns in rural Malawi and are exemplified in traditional proverbs. Traditional proverbs and common expressions offer insight into commonly held truths across societies throughout sub-Saharan Africa. Strong oral traditions allow community beliefs embodied in proverbs to be passed down from generation to generation. In our qualitative study, we conducted 8 individual and 12 focus group interviews with a total of 83 participants across two districts in rural central Malawi with the aim of soliciting context-specific details on men and women’s knowledge, attitudes and practices related to nutrition, gender equality and women’s empowerment. Each interview began by asking participants to share common proverbs related to nutrition. Our qualitative analysis, informed by an indigenous-based theoretical framework that recognises and centres African indigenous knowledge production, yielded six themes: ‘a black dog enters the home’, ‘don’t stay with your hands hanging’, ‘a man is at the stomach’, ‘showers have fallen’, ‘we lack peace in our hearts’ and ‘the hunger season’. Traditional proverbs can provide insight into the underlying causes of hunger and malnutrition. Physicians, nurses and other allied health professionals around the world have a role to play in addressing hunger and malnutrition, which have been exacerbated by climate change. We have an ethical duty to educate ourselves and others, and change our behaviours, to mitigate the root causes of climate change, which are contributing to food insecurity and resultant poor health outcomes in countries like Malawi.

A total of 278 black women (183) and men (95) were administered the Gorham's Proverbs Test and the Shipley Institute of Living Scale (revised). This study compared Abstract scores on the Gorham's Proverbs Test with Vocabulary and Abstract scores on the Shipley Institute of Living Scale. The two tests were remarkably similar in terms of score distributions and susceptibility to the effects of age, perceived socioeconomic level during childhood, education, and perceived quality of education. Analysis also showed that abstract reasoning, as measured by these tests, is not free from the effects of vocabulary skills. Mean scores on both tests were within the range of mean scores previously reported in the literature.

This article uncovers the hidden stepdaughter’s odyssey to Black African Feminism against the backdrop of Kigandan subservient womanhood and Euro-Canadian racism. The first section recounts early childhood experiences of an othered stepchild, followed by teenage anti-misogynist resistance to structural second-class citizenship in a majoritized boy’s school. Subsequent sections narratively capture the lived experiences of transitioning to racialized and subjugated Black womanhood in Germany and Canada, and the becoming of a proud Black African Anti-racist Feminist. Using personal photographs in the narratives makes the experience more present while the Luganda proverbs call forth the uniqueness of an African experience. This article uncovers different strategies of how a young Black African female combats multiple layers of Kigandan cultural subordination and systemic racism in order to excel as a professional immigration consultant and emerging anti-racism and Black feminism scholar.

Full textAbstract:
In this article, we have set ourselves a goal to identify how the conceptions of education contained in Estonian proverbs coincide with the corresponding educational thought in Estonia. We have empirically studied 655 Estonian proverbs that directly refer to a child, growing up, upbringing and parents as well as the methods of education. In the empirical research, we look at whether and how it is possible to semantically categorize and define proverbs based on the educational meanings in their content. To have a clearer system for analysis, we created a comprehensive scheme of categories. The four main categories with subcategories formed during the work. As can be concluded from the analysis of proverbs, the everyday wisdom that lies in them mostly coincides with behaviouristic conceptions of education as interaction and development management. According to educational scientist Heino Liimets, the interaction becomes truly mutual, but only at the highest level of acceptance of the educator’s influence – internal acceptance or interiorization. At lower levels, i.e., only agreeing to or external identification of influence, this is an influence from the educator’s position of power where the educable is passive, subordinate, and obeys commands. This content is characterized by behaviouristic thinking in educational science and can also be observed in proverbs. Behaviouristic beliefs also address the need of the proverbs to take into account the peculiarity of a child in their upbringing, which mainly mean the timeliness of education, i.e., a person can be forced into something only in childhood and youth. Upbringing, education, and learning/teaching are considered practically as synonyms in proverbs and behaviouristic educational science, both being regarded as the management of development from outside a human being. The use of certain educational methods, upbringing, and teaching methods is considered an essential condition for the management of development, education, and teaching, especially in behaviouristic thinking in science. It is a central theme also in proverbs where punishment (incl. physical), ordering, forbidding, disapproving, and causing fear are at the forefront as methods, and praising and “sharing mercy” can be found only to a very limited extent. To speak about Estonian educational scientists, Peeter Põld dealt with the topic of punishment mainly in the first half of the 20th century and Maie Tuulik at the beginning of the 21st century; the latter, however, has completely relied on the ideas of Põld. J. Käis emphasises that the culture, language, and customs of one’s nation are obtained by means of education. Education creates identity and helps socialize. Thus, education occurs as a valuation. The fact that education mediates and reproduces the values and norms valid in society is also clearly evident in Estonian proverbs. In the opinion of Maie Tuulik, modern diversity and ambivalence of values do not allow one clear hierarchy of values to be offered to a child to grow up. According to Põld, the bearer of values should primarily be someone authoritative as an example of education, although Põld himself also sees shortcomings of education based on authority. It levels individuality, promotes passivity and creates conventional values; it does not develop a sense of criticism. The relationships built on authority determine the higher and lower status of someone and, accordingly, the users of and subordinates to the power. Such relationships between parents and children as well as in education appear also in proverbs, which is expected because the world of proverbs expresses the structure of a peasant family characteristic of feudal Estonia. Due to their age, children had a low social status in the family at that time. Social status also depended on the gender. In peasant society, man was the head and provider for the family. Sons had an advantage over daughters: they were given more education and they stayed at the farm. Põld has also associated authority primarily with the father. Thus, education had to reproduce the stereotypically traditional division of roles in a family, which was characteristic of the patriarchal society. The worldview was value-based and normative and divided according to the principle of black and white, containing firm truths about who is a good and who is a bad child. A child who agreed to the upbringing of his/her parents and who respected the parents was considered good. According to Tuulik, such firm beliefs that value the hierarchical nature of relationships should be based on also today. Thus, everyday wisdom and corresponding everyday conscious world found in proverbs is present and reflected in Estonian educational science, especially in the ideas and works of two authors. These are Peeter Põld and Maie Tuulik, who represent a normative Christian-conservative view of upbringing and education, which in science is primarily related to the behaviouristic way of thinking, in which the educable is regarded as a passive object in a relationship of education based on power and authority. Thematically, of course, proverbs are also associated with the thoughts and works of other Estonian educational scientists – in particular, J. Käis, H. Liimets, A. Liimets, J. Orn, and I. Kraav, but in substantive emphasis these scientists represent a cognitive-constructivist, humanistic and hermeneutic-phenomenological way of thinking.

Full textAbstract:
The presented research reveals imagery-metaphoric and phraseological objectivities of the conceptual spheres Soul, Consciousness, Envy, Jealousy and Greed in Polish, Russian, Ukrainian, Czech and Slovak languages and conceptual picture of the world (first of all in proverbs and sayings, idioms, imagery means of secondary nomination both in standard language and its regional or dialectal variants) according to the indication of holistic characteristic and semantic intersection of these concepts. It describes the spheres of their typological coincidence and differences from the point of imagery motivation. It defines the symbolic functions of these ethno cultural concepts (object sphere) with respect to the specificity of manifestation of Envy in archaic texts, believes, in the language of traditional folk culture and archaic expressions with religious sense that reach Christian ideology, ideas of moral purity and dirt, Body and Soul. It has been defined the collocations with the components envy and jealousy in some thesauri and dictionaries in terms of the specificity of interlingual equivalence and expressions of envy and similar negative emotions and their functioning in the Ukrainian and English text corpora. The analysis demonstrated that practically in all compared languages and linguistic cultures Envy is associated with greed and jealousy, psychic disorders with a corresponding complex of feelings, expressed by metaphoric predicates of destruction and remorse that encode the moral and legal aspect of conscience (conscience is a judge, witness and executioner). Metaphor of Envy containing nominations of colours differ in the Slavonic and Germanic languages whereas those denoting spatial, gustatory, odour, acoustic and parametrical meaning are similar. Many imagery contexts of Envy correlate with such conceptual oppositions as richness and poverty, light and darkness; success is associated with the frames “foreign is better than domestic” where Envy encodes the meaning of encroachment upon another's property, “envy is better than sympathy”, “envy dominates where there are richness, success, welfare, happiness” which confirms the ideas of representatives in the field of psychoanalysis, cultural anthropology and sociology. In some languages the motives of black magic, evil eye (in Polish, Ukrainian and Russian) are rooted in the sphere of folk believes and invocations, as well as cultural anthroponyms.

Full textAbstract:
A proverb of the Yoruba people of Nigeria says: ‘However far a stream flows, it never forgets its origin.’ The proverb gives credence to the epochal stories of the human race, and more importantly of the Methodist people in Southern Africa. This article evaluates the history of Methodist people in Southern Africa in the period 1816-2016 from a black theological perspective. First, the paper describes the black theological perspective from which the inquiry into the story of the Methodist Church of Southern Africa (MCSA) is approached, a perspective which is based on the philosophy of black consciousness, the black liberation theology and Methodist theology. Second, the article offers a black theological reflection on selected figures in the history of the MCSA. As a way of concluding, the article considers the prophetic implications of the heritage of Methodism in the MCSA for the Methodist people today.

Full textAbstract:
One of the presuppositions of the present research is that readers and their contexts play a significant role in the interpretation of biblical texts. The key text of this thesis is Proverbs 31: 10-31 and the main readers are African women in a kyriarchal South African (Northern Sotho) context. Given their context of a multiplicity of oppressive forces ( racism, sexism, classism and African culture), how can these women read Proverbs
31: 10-31 appropriately with a view to their liberation? The researcher proposes a new woman's liberationist perspective, a Bosadi perspective, a perspective committed amongst others, to the African-ness of the African woman in South Africa. The question is: If Proverbs 31:10-31 is read from a Bosadi (Womanhood) perspective, how will the Northern Sotho women in a South African context find the text - a text emerging from a kyriarchal Hebraic culture? Will they find it to be oppressive or liberative or will it be found to be containing both elements? The present researcher, like many reformist women liberation biblical scholars (cf some
feminists and womanists ), argues that though the Bible emerged from patriarchal cultures, and contains elements oppressive to women, it also has liberative elements. Through the use of socio-critical hermeneutics, reception criticism and historical-criticism, evidence supporting this came to light as the present researcher re-read Proverbs 31:10-31 from a Bosadi critical perspective. It is therefore argued that when the Bible was used by the previous proponents of apartheid to subordinate people of other races, Black Theologians re-read the Bible from a Black perspective and used it for the racial liberation of Black South Africans. Likewise, an average South African woman, particularly an African woman, is basically a victim of male interpreters who use the Bible to subordinate women. It is the task of all African women to take the responsibility upon themselves to use appropriate tools in re-reading the Bible in order to discover that the Bible does not only alienate them, it is also the liberating word; the word which makes more sense to them because of their relationship with the Word which became flesh (Jn 1:1).D.

Full textAbstract:
I address the origins of the proverb ‘Black but Human’ that emerged from the Afro-Hispanic oral tradition and the ways in which colour and social status are compounded. There is documentary evidence that the word ‘black’ was used as a mark of the inferior social condition of slaves and that it designated a diversity of ethnic backgrounds that included people with contradictory colour classifications. I am concerned with the Afro-Hispanic beliefs that are embodied in this proverb and are conveyed in the recently discovered black carols, written by Afro-Hispanic slaves and ex-slaves in the Spanish black confraternities, later reappropriated by Hispanic white writers. These work songs centre on the assertion that Africans are human in spite of their legally enforced status as commodified objects with no rights. They focus on the association between being human and the possession of a soul that becomes white as the result of baptism.

Judith Weisz's story returns us to the national politics of drug risk management and finds an altered risk assessment environment for Depo-Provera, because the FDA decided to eliminate animal studies and rely solely on improved World Health Organization human clinical trial data, which paved the way for the agency to approve the drug for contraception in 1992. Marketing approval came with the condition that Upjohn conduct a post-approval study of a new risk: osteoporosis. When clinical trials confirmed this risk, the FDA revised the drug’s package insert in 2004 to include a black box warning of the risk of osteoporosis and a recommendation that the drug's use be limited to two years. In Depo-Provera's post-approval world, Anne MacMurdo's story is told by women who claimed that the drug caused their osteoporosis. Their stories, like hers, raise medical malpractice and products liability issues, and they, too, faced formidable obstacles. None of their cases, unlike hers, went to trial. Pfizer, Upjohn's corporate heir, had their cases dismissed on motions for summary judgment. Her story explains how Pfizer was able to use Depo-Provera’s package labelling, state products liability law, the learned intermediary doctrine, and expert evidence to avoid liability.

This chapter looks into Claude McKay's “Amiable with Big Teeth: A Novel of the Love Affair between the Communists and the Poor Black Sheep of Harlem,” which was written during the Second Italo-Abyssinian War. McKay's novel hinges upon the question of what it means to be an “authentic” Ethiopian imperial representative. It focuses on one of the novel's characters, Alamaya, who admits cagily that a signed letter from the emperor establishing his bona fides “was authentic but not genuine”; later, as part of a scheme to raise funds for the Ethiopian cause, Alamaya and his secret communist colleague “invent” an Ethiopian princess by costuming a local Harlem woman. But in fact, it was Professor Koazhy, a costumed figure modeled after Marcus Garvey, and not the meek visiting Ethiopian prince Alamaya, who proves to be the “authentic” Ethiopian prince. The chapter also explains how the existence of a centralized Ethiopian empire would challenge the viability of an imagined extra-imperial network of black internationalism.

Proving the correctness of a program, even the simplest one, is a complex and expensive task; but, at the same time, it is one of the most important activities for a software engineer. In this chapter, we explore the use of theorem provers to certify properties of software; in particular, two different proof-assistants are used to illustrate the method: Coq and PVS. Starting with a simple pedagogic example, a sort algorithm, we finally reproduce the same approach in a more realistic scenario, a model of a block-allocation algorithm for a video-on-demand server.

Using marquillas cigarreras, the small printed papers in which bundles of cigarettes were sold, as case studies, this chapter analyzes the development of nationalist sentiment and the iconography of national identity through the visual imagery of commodities. Marquillas cigarreras featured a virtually encyclopedic array of imagery: from natural history, architectural monuments, almanacs, serials, military uniforms and insignia, some of the most memorable marquilla series depicted costumbristic scenes of Cuban life and types, including mulatas, blacks, proverbs, literary figures and social satire. The chapter discusses the significance of cardinal Cuban products—tobacco and sugar—in the context of economic, cultural and ideological conditions, and analyzes the ways they are presented and consumed through commodity consumption. These products were crucial to the economy and the symbolic products linked to national identity, as evident on marquillas. Furthermore, their production is inextricably linked to the colonial system, including African slavery, European mercantilism and European immigration.

This chapter derives some basic properties of the plaid model. It is organized as follows. Section 2.2 deals with the symmetries of the plaid model. First, it deals with the unoriented model and then considers the oriented model. Section 2.3 proves the technical lemma that each unit integer segment contains exactly two intersection points. The work in this section reveals the nice geometric way that the slanting lines intersect each unit integer square. Section 2.4 establishes the following result: Within each block, there are exactly two lines of capacity k for each even k ɛ [0, ω]. Moreover, within the block, each line of capacity k has exactly k light points on it (when double points are appropriately counted). Section 2.5 establishes a subtle additional symmetry of the plaid model.

This chapter explores some consequences of the results in Chapter 2, especially Theorem 2.3. It suggests that Theorem 2.3 gives a way to extract information from the geometry of the low capacity lines. Section 3.2 proves that, relative to the parameter p/q, the 0th block always contains a polygon whose projection onto the X-axis has diameter at least (p + q)/2. Section 3.3 elaborates on the theme in Section 3.2 to show how to extract increasingly fine scale information about the plaid polygons. Section 3.4 explains how to augment the idea in Section 3.3 to make it more useful. Section 3.5 shows how the ideas from Section 3.3 sometimes explain why the plaid model looks similar at different rational parameters.

Full textAbstract:
This chapter proves the geometric picture of double resonance described in Chapter 4. There are two cases. In the simple critical homology case, the chapter shows the homoclinic orbit can be extended to periodic orbits both in positive and negative energy. The union of these periodic orbits forms a normally hyperbolic invariant manifold (which is homotopic to a cylinder with a puncture). In the non-simple homology case, the chapter demonstrates that for positive energy, there exist periodic orbits. The strategy is to prove the existence of these periodic orbits as hyperbolic fixed points of composition of local and global maps. A main technical tool to prove the existence and uniqueness of these fixed points is the Conley-McGehee isolation block.

Full textAbstract:
Abstract This paper introduces the concept of a process capability matrix — an ordered set of dimensionless parameters that capture information on a manufacturing system’s response to noises. The matrix captures information on the magnitude of noise, sensitivity to noise, and tolerance to variation. Algorithms and equations are presented that use the matrix to compute the yield of a manufacturing system. The method proves to be accurate on real engineering problems for which existing techniques are inadequate due to statistical correlation among product acceptance criteria. The process capability matrix also proves useful in a new type of block diagram of production systems. The block diagrams are shown to be useful in evaluating the effectiveness of feedforward control strategies for variation reduction. An electronics assembly process serves as an example of the algorithms and their use in design decision making.

Full textAbstract:
This paper shows how reliability block diagrams can be used as a decision making tool. The premise behind the idea is that classical decision analysis while very powerful, does not provide tractability in assessing utility functions and their use in making decisions. Our recent work has shown that visual representation of systems using a reliability block diagram can be used to describe a decision situation. In decision making, we called these block diagrams decision topologies. We show that decision topologies can be used to make many engineering decisions and can replace decision analysis for most decisions. The paper proves that at the limit, using decision topologies is entirely consistent with decision analysis for both single attribute and multiattribute cases. The main advantages of the proposed method are that (1) it provides a visual representation of a decision situation, (2) it can easily model tradeoffs, (3) it allows binary attributes, (4) it can be used when limited information is available, and (5) it can be used in a low-fidelity sense to quickly make a decision. The paper details the theoretical basis of the proposed method and highlights its benefits. An example is used to demonstrate how decision topologies can be used in practice.

Abstract In order for students to enhance their understanding of engineering concepts, hands-on experience proves to be essential. Incorporating the design component in undergraduate engineering education has been an immediate and pressing concern for educators, professional societies, industrial employers and agencies concerned with national productivity and competitiveness. It is crucial to enhance undergraduate design and research experiences to meet both societal needs and the growing job-market demands. The University of the District of Columbia (UDC), the District of Columbia’s only public institution of higher education, and a historically black college and university (HBCU), had recently modernized its undergraduate curricula in engineering to meet that need. This paper presents a case study of recent implementation of student experiential learning approach through undergraduate research experience course (MECH 302). This student group participated in the 2019 US National Aeronautics and Space Administration Revolutionary Aerospace Systems Concepts – Academic Linkages (RASC-AL) Challenge, in which they will develop concepts that may provide full or partial solutions to specific design problems and challenges currently facing human space exploration.

Soft robotics integrates compliant actuators and sensors that expand design possibilities beyond classic robotics based on rigid modular components. In particular, deformable elastomer-based actuators used in soft robots, such as air-muscles, offer the possibility of having large numbers of embedded degrees of freedom. However, air-muscles fatigue life and strain capability call for a tradeoff, limiting their practical use in demanding applications such as physical rehabilitation, medical robotics, and mobile robots. This paper presents the design of a durable high-strain air-muscle composed of a silicone tube and an axially elastic sleeve (radially rigid), which integrates a flexible Dielectric Elastomer (DE) position sensor. The uniformity of the sleeve, by opposition to usual braids, makes for a reinforcement without local stresses that cause membrane failure. Designed based on fatigue failure principles, this air-muscle withstands 145 000 cycles at 50 % elongation, which demonstrates its potential as a durable high-strain actuator. Performance maps of the air-muscle confirm good linearity between force, pressure and strain and demonstrate bi-directional force capability. Furthermore, the integration of a DE sensor allows for accurate position control of the air-muscle (0.17 mm), making the air-muscle/sensor unit a relevant building block for complex soft robotics systems. The all-polymer high-strain actuator/sensor unit proves to be accurate and durable as well as cost-effective, thus making it ideal for soft robotics applications requiring large numbers of actuators and integrated sensing.

Full textAbstract:
Abstract Traditional Microbial Enhanced Oil Recovery (MEOR) technology assumes the oil recovery is increased by the biosurfactant generating by the subsurface bacteria. However, we identified that increased recovery factor is mainly contributed by stimulating the indigenous bacteria to plug the preferred waterflooding channels, which was proved at laboratory and some high-permeable oilfield, but never implemented in the waterflooding of tight oilfield. This paper presents a comprehensive study on Bio-diversion technique by stimulating indigenous bacteria covering lab research and filed operation lasting 18 months. The lab research comprised: (1) feasibility research using modified recipe and field sample on the stimulation of indigenous microorganisms; and (2) Evaluation of effectiveness of the stimulation based on lab results. A field pilot, consisting of 10 injectors, 10 producers, injecting and producing from multi-zones, reservoir temperature is about 160 F, permeabilities range from 30 md to over 100 md, daily water injection rate is about 2,000 BWPD, pre-treatment water cut is over 90%. It is observed that the water cut has decreased from 98% to 80% gradually (3-6 months after injection). Besides, the water injection index test indicates that the injection profile becomes more evenly after 9 months of microbial nutrient injection because the stimulated bacteria reduce the permeability of more permeable zones and reduce the permeability heterogeneity in the vertical direction. Sharing the field results with the industry may inspire the operators to consider one alternative environmentally friendly and cost-effective approach to increase the recovery factor of tight oil reservoirs. From the technical viewpoint, the field pilot proves that the major mechanisms of MEOR is sweeping the unswept oil by injecting the microbial nutrient to the reservoir to stimulate the indigenous bacteria to block the preferred waterflooding channels.

Full textAbstract:
Optimization in brown field developments is always challenging in terms of cost. One of it is XY Field, Rimau Block, South Sumatera with more than 70% of artificial lift is Electrical Submersible Pump (ESP). At ESP wells that are already running at maximum operating frequency of 60 Hz, some are still having problems to optimize their potential. The option to replace the pump with a higher rate is less of an option due to high cost. This leaves an opportunity to gain oil production by increasing frequency above 60 Hz. Upon discussion with the ESP Principal on the risks and possibilities, a trial was then planned for 3-wells. Candidates are selected from the list of ESP wells with the following criteria such as already operated at 60 Hz, still have sufficient fluid submergence, and based on simulated motor load at 70 Hz is still at safe motor load level. Frequency was increased gradually while continuously monitoring ESP Parameters (motor load, voltage and harmonic). It is also necessary to monitor the cable temperature as it is directly affected by the frequency changes. For each frequency increment, a well test is also performed to monitor the production changes. The trial was done on 3-wells (XY-364, XY-370 and XY-378), with the following promising results. XY-364 and XY-378 successfully reached the targeted 70Hz, while XY-370 stopped at 65Hz due to a cable temperature issue. Oil gain from this optimization was 48 BOPD with 1,043 BLPD and similar BS&W profile. ESP operation still normal until present day with all parameters at acceptable range. There were, however, challenges found during the trial. Cable temperature of XY-364 increased at junction box and found cable scun loosen. The problem was solved by replacing the cables. For XY-370, found temperature increment at moulded case circuit breaker during trial at 65 Hz. It was decided to hold at existing frequency. Unbalanced motor load at XY-364 and broken capacitor at XY-370 occurred at Harmonic Filter. The problem was solved by replacing the capacitor. The trial proves that we can operate ESP higher than base frequency (60 Hz) and resulted in decent oil gain. This opens an opportunity in ESP optimization above 60 Hz at an even larger scale.

Abstract This paper presents a Computational Fluid Dynamic (CFD) simulation for dry air/water-liquid and two-phase flow mixing in a vertical inverted U-tube using the mixture multiphase and turbulence models. This study is to investigate the flow behaviors and underlying some physical mechanisms encountered in dry air/water-liquid flow in the inverted U-tube. Water flows through the inverted U-tube while the dry air is entrained using the side-tube installed after the water flow downward. The inverted U-tube is tested at water mass flow rates of 2,4,6 and 8 kg/s, air mass flow rates, 0.000614–0.02292 kg/s, with dry air volume fractions 0.2–0.9. The obtained results are compared with the experimental data for model validation and the present CFD model is able to give an acceptable agreement. Also, the results show that, at water mass flow rate of 2 kg/s, there are vortices and turbulent intensity disturbances are noticed at the inverted U-tube higher part, which refers to an air entrainment occurrence from the side-tube. Theses disturbances starts to be stabilized at air mass flow rate around 0.00736 kg/s and air volume fraction, αa = 0.75. This means, if the air mass flow rate increases above this limit, the air entrainment may be blocked. On the other side, at water mass flow rate of 4 kg/s, there are little noticed disturbances until air mass flow rate of 0.00368 kg/s and αa = 0.43 and thereafter stabilized. After this point for water mass flow rate of 4 kg/s, increasing air mass flow rate may block the water flow and the whole inverted U-tube system possible stop flowing. Therefore, this study is able to estimate the required operational conditions and mass ratios for stable air entrainment process. Beyond these operational conditions, air entrainment may be blocked and the whole system discontinues its normal induced gravitational flow. In addition, this study proves that the inverted U-tube is able to generate a vacuum pressure up to 53.382 kPa based on the present geometrical configuration. This generated low-pressure by the inverted U-tube can be used for engineering applications which are working under vacuum and need continuous evacuating form the dry air and non-condensable gases. Furthermore, these findings motivate the utilizing of inverted U-tube for the air evacuation purposes for less power consuming in power plants.

Full textAbstract:
Abstract Cuttings data has always been neglected or forgotten as a source of information by many operators. In some areas, it is even common practice to throw away cuttings in order to reduce cost. However, cuttings data can yield a great amout of information to provide great value and support to drilling operations, as well as reduce potential downhole risks. This was evident in wells drilled in remote Western regions of China, where wells typically have high temperature high pressure (HTHP) formations with a true vertical depth ranging between 4000-7000 meters and target formation temperature between 150-160 degrees Celcius. Due to severe drilling conditions, the measurement tools of Logging While Drilling (LWD) and Measured While Drilling (MWD) are at high risk of running into holes. Even due to the high formations’ temperatures is over the bottom line of LWD and MWD tools, the sensors of LWD and MWD cannot work efficiently in such circumstances, increasing the drilling risk and expense. Thus, "blind" drilling is the most reasonable economical choice for local operators. Without sufficient real-time formations’ information, the drilling uncertainties dramatically increase. The fluid loss, pipe stuck, as well as drilling bit damages frequently occur. Currently, there is no successful well that accesses to the target reservoir. The data from the wireline logs and cores cannot be available, as the well is the first exploration well in the block; however, during drilling, only drill cuttings are available for peoples. The creative cutting-based petrophysics models are built for the formation analysis that is able to provide rock density, cuttings gamma, Delta Time of Compressional Acoustic (DTC), Unconfined Compressional Strength (UCS) Index, Caliper Index, Brittleness Index, and Hydrocarbon Index from the cuttings samples at the wellsite on a near-real-time basis. This data can help people quantitatively and qualitatively evaluate the downhole formations on a near-real-time basis and can help people to make a more reasonable decision, and therefore, reduce the drilling risk within a controlled level. The authors provide the several cases to study the cutting models into drilling events, and proves the models are consistent with log and core data, and match the drilling parameters and like ROP, and pumping pressure, as well as torque, and bit performance. LWD and MWD are unable to run into the hole due to high formation pressure and extreme risky hole. The field portable XRF instrument is applied, and the mineralogy and elements input into the models. The cuttings petrophysics analysis application can provide the valuable information for drilling engineers to drill the wells to TD.
